인터넷 개인 게임방송과 저작권 -아프리카 TV 사례를 중심으로-

심성우 ( Sungwoo Sim ) 연세대학교 법학연구원 의료·과학기술과 법센터 2014 연세 의료·과학기술과 법 Vol.5 No.2

Internet Webcasting is now growing as a new media which can replace TV. In Korea, leading Internet Webcasting service IS AfreecaTV, and a majority of channels in AfreecaTV is Game Webcasting. However, the Copyright Law of Korea doesn``t regulate clearly about Internet Webcasting, and it``s difficult to legally define the parties involved in this service. Furthermore, a problem of copyright possession and infringement is happening. First, copyright of game is admitted by precedents. Game is a combined work of image, music, program, material, and etc. Also, it is cooperated work by producer, designer, programmer, and etc. A gamer or commentator should be recognized as a performer in Game Broadcasting. Secondly, Internet Webcasting is divided into a Streaming type and a Demanding type. The streaming type we should focus on has both simultaneity-which IS a feature of ``broadcasting``- and interactivity-which is a feature of ``transmission``. The current Copyright Law of Korea doesn``t have suitable definition and regulation for Internet Webcasting. Thirdly, based on the current Copyright Law of Korea, a BJ-Broadcasting Jacky- of Internet Webcasting IS an owner of copyright basically, but BJ is also a performer and broadcasting station, A platform like AfreecaTV is sharing some role of broadcasting station with BJ, and a viewer can also be performer or an owner of copyright. It means that a legal position of the parties involved in this service is difficult to define by the current Copyright Law of Korea. Fourthly, Internet Game Web casting is usually provided in two formats, namely, the format of webcasting the others`` competition and the format of webcasting the game play of BJ himself. In Korea, some famous BJs are earning more than 100 million won a year. In United States of America, Twitch TV-a game only Internet Web casting service IS becoming huge enough to surpass a traditional TV cable channel. Fifthly, the use of game in Internet Game Webcasting is mostly unauthorized use. This means that BJ is infringing a copyright of the game company. A platform like AfreecaTV is also violating Copyright Law of Korea by ignoring the copyright infringement. The platforms must deal with this problem at the front line, and all the other parties such as BJ, association of e-sports, game companies, and etc. should also try hard to solve the problem. As a conclusion, Copyright Law of Korea must be amended to settle the unstable legal character of Internet Web casting and the parties involved. Also, the copyright infringement should be dealt by the parties involved while not neglecting an effort for industrial advance at the same time.

Despite of numerous research on motivation in the field of tourism, little research has been conducted for identifying motivations of the Korean DMZ visitors and then segmenting them with distinct subgroups for practical marketing strategies. In this respect, this study aims to identify the underlying dimensions of motivation for the DMZ visitors, using a factor analysis; to segment the DMZ market, using a two step cluster analysis based on derived motivation factors; to investigate any difference between two segments with respect to value; and to examine any differences between market segments with respect to socio-demographic and behavioral variables. The results of this study show that five underlying motivation dimensions were derived: novelty, adventure, information, peace, and nostalgia. The results of two step cluster analysis indicate that two distinctive segments were identified: passive and active motivation visitors. These two segments were significantly different with respect to purpose of visit, type of partner, information sources, income, age, marital status, and occupation. Additional factor analysis for the value of visiting DMZ was performed. In the process of factor analysis, three factors of value(overall value, emotional value, and monetary value) were derived. The results of t-test indicate that statistically significant difference existed between two segments with respect to overall value.

Sung Woo Sim(심성우),Young Lae Moon(문영래),Jung Hun Kang(강정훈) 대한견주관절의학회 2012 대한견주관절학회지 Vol.15 No.2

목적: 세가지 기원의 줄기 세포 분화능과 면역표현형을 평가하고자 하였다. 대상 및 방법: 견봉하 점액낭과 골수, 탯줄 혈액 세 개의 군에서 세포를 채취하였다. 견봉하 점액낭과 골수는 견관절 수술 환자군에게 임상적 동의 하에 수술중 채취하였다. 각각의 채취된 세포 및 탯줄 혈액에 대하여 계대 배양을 시행하여 신경 분화군, 지방 분화군, 골 분화군을 평가하였으며 세포 표면 항체를 밝히기 위해 유동세포분석법을 이용하였다. 결과: 견봉하 점액낭 유래 세포에서는 신경분화와 지방 분화는 8예 모두 (100%)에서, 골분화는 8례 중 5예 (62.5%)에서 성공할 수 있었으며 골수 유래 세포의 경우 신경 및 지방 분화 유도한 6례 및 5예 모두 (100%) 분화에 성공하였으나 골분화 유도는 5예 중 4예 (80%)에서 얻을 수 있었다. 반면 탯줄 유래 세포 분화 연구의 경우 신경 분화 유도 67례 중 65예 (97%)에서 지방 분화연구 54예 중 29예 (53.7%)에서 골 분화 연구 57예 중 39예 (68.4%)에서 성공할 수 있었다. 결론: 탯줄 유래 줄기세포의 분화능과 비교하였을 때 견봉하 점액낭 및 골수 유래 줄기세포의 분화능이 우수함을 알 수 있으며 이는 향후 세포 치료에 있어서 안정성 있는 치료 제공자가 될 수 있을 것으로 보이며 향후 생체 실험 연구의 참고 자료로서도 가치가 있을 것으로 보인다. Purpose: To evaluate the differentiation potential of stem cells and their immunophenotype from 3 different sources. Methods: Our study involved three stem cell sources-subacromial bursal tissue, bone marrow, and umbilical cord blood. We obtained the subacromial bursal tissue and bone marrow from the patients undergoing shoulder surgery. After collecting the sample, we applied specific induction media for neurogenic, adipogenic and osteogenic differentiation. Also, flow-cytometry analysis was done to reveal the cell surface antigens. Results: We obtained 100% (8 cases) neural and adipogenic differentiation, but 62.5% (5 of 8 cases) osseous differentiation among the subacromial bursal tissue group. Bone marrow derived cells showed 100% neural (6 cases) and adipogenic (5 cases) differentiation, but 80% (4 of 5 cases) osseous differentiation. Umbilical cord blood derived cells revealed 97% (65 of 67 cases) neural, 53.7% (29 of 54 cases) adipogenic and 68.4% (39 of 57 cases) osseous differentiation. Immunophenotype analysis revealed that surface markers of bone marrow, subacromial bursal cell and umbilical cord blood derived mesenchymal stem cells are different from each other. Conclusions: Mesenchymal stem cells are potential agents in regenerative medicine and are characterized by expression of surface markers and by their differentiation potential. Our study with stem cells from subacromial bursal tissue, bone marrow and umbilical cord discovered that each stem cell has unique differentiation potential and function based on its origin. Various stem cells show multi-lineage differentiations in vitro which can be correlated to in vivo conditions.

Background: The authors evaluated the hemodynamic effects of body position measured by esophageal Doppler monitor (EDM) during laparoscopic cholecystectomy or gynecologic laparoscopic surgery. Methods: Fifty patients scheduled to undergo laparoscopic cholecystectomy (Group C) or gynecologic laparoscopic surgery (Group G), were divided into two groups. Pneumoperitoneum was instituted by CO2 gas and the intraperitoneal pressure was kept under 12 mmHg. Hemodynamic parameters at critical points were measured by the use of EDM: before skin incision (T1), 5, 10 and 15 min after changing position (T2, T3 and T4), and 5 min after CO2 exsufflation (T5). Results: MAP (mean arterial pressure) was significantly higher in Group G when compared with Group C 10 min after changing position (T3) (P < 0.05). CO (cardiac output) was significantly decreased in Group G when compared with Group C 10 min after changing position (T3) (P < 0.05). And there were not significant differences in HR (heart rate) between two groups. PV (peak velocity) was significantly decreased in Group G when compared with Group C 10 min after changing position (T3) (P < 0.05). And there were not significant differences in FTc (corrected flow time) between two groups. But FTc in Group C was restored after CO2 exsufflation, FTc in Group G was not restored after CO2 exsufflation. Conclusions: Changing position in the gynecologic laparoscopic surgery group can elevate MAP and decrease CO. Therefore, careful caution is required in patients with cardiovascular disease who are undergoing gynecologic laparoscopic surgery.

최석원,한성우,심완주,최동주,김용진,유병수,황경국,전희경,신미승,유규형 대한의학회 2018 Journal of Korean medical science Vol.33 No.25

Background: We aimed to evaluate effect of heart rate (HR) reduction on left ventricular reverse remodeling (LVRR) in Korean patients with heart failure with reduced ejection fraction (HFrEF). Methods: Ambulatory patients with HFrEF, who had paired echocardiograms, N-terminal prohormone brain natriuretic peptide (NT-proBNP), and global assessment score (GAS) at baseline and 6-month (n = 157), were followed up on preset treatment schedule with bisoprolol. Results: The LVRR occurred in 49 patients (32%) at 6-month. In multivariable analysis, independent predictors associated with LVRR were use of anti-aldosterone agent (odds ratio [OR], 4.18; 95% confidence interval [CI], 1.80–9.71), young age (OR, 0.96; 95% CI, 0.92–0.99), high baseline HR (OR, 3.76; 95% CI, 1.40–10.10), and favorable baseline GAS (OR, 1.73; 95% CI, 1.06–2.81). Beneficial effect of bisoprolol, in terms of LVRR, NT-proBNP, and GAS, was remarkable in the high HR group (baseline HR ≥ 75 beats per minute [bpm]), which showed a large HR reduction. Conclusion: High baseline HR (≥ 75 bpm) showed an association with LVRR and improvement of NT-proBNP and GAS in patients with HFrEF. This seems to be due to a large HR reduction after treatments with bisoprolol. Trial registry at www.ClinicalTrials.gov, NCT00749034.

교수자의 커뮤니케이션 스타일 및 라포형성이 대학생활만족도에 미치는 영향: COVID-19 상황에서 온라인 수업을 대상으로

박슬기,심성우 한국관광연구학회 2022 관광연구저널 Vol.36 No.11

본 연구의 목적은 COVID-19 팬데믹 상황에서 온라인 수업을 대상으로 교수자의 커뮤니케이션 스타일과 교수자와 학습자 간의 라포 및 대학생활만족 간의 영향관계에 대해 검증하는 것이다. 연구 수행을 위해 편의표본추출방법을 사용하여 2개월간 서울에 위치한 2년제 대학의 학생들에게 온라인 설문조사를 실시하였다. 변수들 간의 영향 관계를 검증하기 위해 두 개의 가설을 설정하였으며, 가설 검증을 위해 AMOS을 활용한 구조방정식모형분석을 실시하였다. 분석 결과는 다음과 같다. 첫째, 신뢰협력형 커뮤니케이션 스타일은 라포에 유의미한 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 라포는 대학생활만족도에 유의미한 긍정적인 영향을 미치는 것으로 제시되었다. 추가적으로 교수자의 커뮤니케이션 스타일과 라포에 있어서 성별과 학년에 따른 차이는 제시되지 않았다. 결과적으로 교수자와 학습자 간의 라포를 형성하기 위해서, 교수자는 온라인 수업을 운영할 때 학생들의 의견에 주의를 기울이고 신뢰를 심어줄 수 있는 커뮤니케이션 방법들을 활용하는데 초점을 맞추어야 하며, 이러한 과정은 COVID-19 팬데믹 상황 하에서 학생들의 대학 생활에 대한 만족도를 증가시킬 수 있다. 그러므로 교수자들은 온라인 수업에서 학생들에게 신뢰와 협조를 표현할 수 있는 효과적인 방법을 강구할 필요가 있으며, 학교 차원에서는 라포 수준을 향상시키기 위해 교수자들의 커뮤니케이션 스킬을 개발할 수 있는 실질적인 지원과 프로그램을 제공할 필요가 있다.
